谷歌地图片段设置在点击侦听器剂量不起作用

Question

我想在全屏项目中创建一个谷歌地图片段，然后当我触摸谷歌地图片段时调用一些函数，但当我触摸谷歌地图片段集时，点击侦听器不起作用这是我的XML部分和Java部分

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:keepScreenOn="true"
    />
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fullscreen);
    mVisible = true;
    mControlsView = findViewById(R.id.fullscreen_content_controls);
    mContentView = findViewById(R.id.map);
     // Set up the user interaction to manually show or hide the system UI.
    mContentView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            toggle();
        }
    });
    // Upon interacting with UI controls, delay any scheduled hide()
    // operations to prevent the jarring behavior of controls going away
    // while interacting with the UI.
    findViewById(R.id.dummy_button).setOnTouchListener(mDelayHideTouchListener);
}

创建 xml 布局文件：

content_main.xml包含 MapFragment，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.journaldev.MapsInAction.MainActivity"
    tools:showIn="@layout/activity_main">
    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_gravity="center"
        android:layout_height="match_parent"
        />
</RelativeLayout>

主活动.java定义如下：

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;

import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {
    SupportMapFragment mapFragment;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mapFragment.getMapAsync(new OnMapReadyCallback() {
                    @Override
                    public void onMapReady(GoogleMap googleMap) {
                        googleMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
                        googleMap.addMarker(new MarkerOptions()
                                .position(new LatLng(37.4233438, -122.0728817))
                                .title("LinkedIn")
                                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));
                        googleMap.addMarker(new MarkerOptions()

                                .title("Facebook")
                                .snippet("Facebook HQ: Menlo Park"));
                        googleMap.addMarker(new MarkerOptions()

                        googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(37.4233438, -122.0728817), 10));
                    }
                });
            }
        });
    }
    @Override

我认为这里的想法是他想让地图片段像视图一样，其中片段用作地图查看器，他想使其可点击，因此点击操作将调用他在其中实现的代码。

我

之前遇到了这个问题，我意识到片段不能用作视图，因为它里面的材料是应该像视图而不是碎片一样处理的材料。但是对于片段中的地图，有一个技巧可以使其看起来像"视图">

首先，您需要设置地图的片段：

<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

然后在保存片段的片段或活动类中，

class FormFragment : Fragment(), OnMapReadyCallback, GoogleMap.OnMapClickListener{
lateinit var binding: FragmentAddplaceFormBinding
lateinit var map: GoogleMap
override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    binding = FragmentAddplaceFormBinding.inflate(inflater, container, false)
    binding.map.onCreate(savedInstanceState)
    binding.map.onResume()
    try{
        activity?.let { MapsInitializer.initialize(it.applicationContext) }
    }catch (e: Exception){
        e.printStackTrace()
    }
    binding.map.getMapAsync(this)        
    return binding.root
}

正如你所注意到的，这个类实现了GoogleMap.OnMapClickListener，它将用于使"可点击"。

你应该能够实现成员，你会得到这些

// This is the one that will do the trick
override fun onMapClick(p0: LatLng) {
     // Your code here to make it look like the map is clicked on touch
}
override fun onMapReady(p0: GoogleMap) {
}

然后像这样做

override fun onMapClick(p0: LatLng) {
     Toast.makeText(context, "You clicked on the map, Congrats!", Toast.LENGTH_SHORT).show()
}
override fun onMapReady(p0: GoogleMap) {
     map = p0
     p0.setOnMapClickListener(this)
     
     // These settings can be changed to whatever you desired, 
     // but because I want to make it look like a decend Map Viewer, 
     // so I disable all of these
     with(map.uiSettings){
        isZoomControlsEnabled = false
        isCompassEnabled = false
        isMyLocationButtonEnabled = false
        isZoomGesturesEnabled = false
        isScrollGesturesEnabled = false
        isRotateGesturesEnabled = false
        isTiltGesturesEnabled = false
    }
}

希望这能有所帮助
